Abstract :
A compact, wide-dual-band antenna is designed to satisfy 2.4-2.5 GHz and 5.0-6.0 GHz Bluetooth and wireless LAN applications. The antenna is composed of a rectangular dielectric resonator (DR), a foam former and a grounded inverted-L conductor plate with L-shaped slot. The first band with bandwidth 120 MHz is derived from the inverted-L antenna mode. The bandwidth of the second band is over 1 GHz, which is generated by two hybrid modes that are very close to each other. These modes are produced by the DRA and parasitic plate. The wide bandwidth and dual-band required for different Bluetooth and wireless LAN applications are readily achieved using the proposed antenna structure. Radiation patterns give omni-directional coverage in the azimuth plane. Thus this antenna satisfies simultaneously almost all the Bluetooth and wireless LAN application needs at different frequencies. The design is surface mountable and can be realized by LTCC technologies to obtain low cost and light weight.
